Exterior Architectural Capitals
Polure exterior architectural capitals add grandeur and timeless classical framing to building facades, porch pillars, and entrance portals. Formed from high-density rigid polyurethane (150-220 kg/m³), these exterior capitals boast wood-like mechanical durability and high impact resistance without cracking under severe weather. Featuring a closed-cell matrix with water absorption under 1%, they resist rain, snow, freeze-thaw cycles, and mold. Certified B2 for fire safety and dimensionally stable from -100 °C / +80 °C, each capital comes factory pre-primed with white acrylic primer. Installation is completed by applying continuous polyurethane assembly adhesive to rear contact edges, securing with countersunk mechanical screws, filling holes with facade filler, sanding smooth with 180-220 grit, and painting with UV-resistant exterior topcoat paint.
Frequently Asked Questions
What material is used for Polure exterior architectural capitals?
They are manufactured from high-density rigid polyurethane (150-220 kg/m³), offering wood-like strength and B2 fire rating.
Are exterior architectural capitals weather-resistant?
Yes, with water absorption below 1% and stability between -100 °C / +80 °C, they withstand rain, frost, and UV rays when painted.
How do you install exterior architectural capitals?
Apply continuous PU assembly adhesive on contact edges, secure with mechanical screws, fill screw holes with filler, sand, and paint.
Is silicone allowed for exterior architectural capitals?
No, silicone is strictly forbidden as it lacks long-term bonding strength. Always use polyurethane assembly adhesive with mechanical screws.
